Title: Remote control of valve filaments in wireless sets
IPC: H04B1/16
Filed: 1927-08-02
Abstract: 297,918. Angel, F. S. Aug. 2, 1927. Receiving-sets, construction of.-A wireless receiving-set is switched on and off from one or more remote listening points by a polarized relay controlled by a dry cell and a reversing switch at each remote point. The polarized relay is incorporated as a unit with the output transformer (or the choke-capacity output circuit) of the last amplifying valve. As shown in Fig. 1, the last valve 5 of the set includes a choke coil 1 in its plate circuit, and the plate 4 is connected to the remote loud-speaker 19 through a condenser 6, the return connection for the loudspeaker being either through earth as shown, or through an additional lead. The unit A adjacent the set also includes a polarized relay 8, the armature of which controls the filament circuits, and if desired the plate circuits also, of the set. The unit B at the remote point includes a dry cell 13, loud-speaker terminals or jack 18, 21 and a reversing switch 12 arranged to connect the cell 13 with either polarity to the relay 8. The switch 12 is preferably of the spring-released or push-button type automatically returning to the off position when released by the operator. Closure of the switch in one direction causes the relay 8 to close the filament circuits, whilst closure in the other direction opens the filament circuit. Further control points may be connected by leads 20, 22. An output transformer may replace the choke 1. In a modification shown in Fig. 2, a number of remote control stations B. C, D are connected in series. The unit A adjacent to the set is the same as in Fig. 1, but the reversing-switches 23 of the remote units B, C, D have additional contacts 30, and the loud-speakers are plugged into sockets which in addition to the springs 32 for connecting up the loud-speakers comprise also additional contactpairs 22, 31 which are normally closed but are opened by the plug-in action. The contacts 22, 31 maintain the continuity of the remote control circuit at those units where no loud-speaker is in circuit, whilst the relay 8 for switching the set on and off is under the control of the switch 23 at the operative unit, at which the contacts 30 bridge the terminals 9<a>, 16 in the return wire R when the switch 23 is swung in either direction. The set may thus be switched on at any remote unit, whilst switching off is effected at the last unit in use. The filament and plate circuits of the set may be supplied from house mains.

Title: Improvements in or relating to photographic cameras
IPC: G03B13/20
Filed: 1932-07-21
Abstract: 388,997. Photographic cameras. VOIGTL€NDER & SOHN AKT.-GES., 7, Campestrasse, Brunswick, Germany. July 21, 1932, No. 20592. Convention date, Nov. 26, 1931. [Class 98 (i).] The lens front of a camera is connected with the distance-finder by means such that the camera lens may be focussed on operation of the distance-finder with the camera either in the folded or the open position. As shown in Figs. 1 and 2, a distancefinder comprising an eyepiece 17, objectives 18, and prisms 19 is mounted in the camera casing 16. One prism 19 is mounted on a lever 1 connected to a lever 8, the bottom end of which is held in contact by means of a spring 10 with a lever 3 having a toothed segment 5 meshing with a pinion 6 engaging gearing operated by a knob 7. On the baseboard 20 is linkwork 11, 21 jointed together at 22, and jointed at one end 12 to the lever 3 and at the other end 13 to a slide 23 slidable on a rail 25 and connected to the lens front 14 which is provided at the other side with a guideway 26. As shown in Fig. 5, the lens front 14 is provided with a housing in which is a spring 32, attached at its outer end to the housing and at its inner end to an arbor 33 to the bottom end of which is secured a sprocket wheel 34 on which is trained a chain 28 attached at its free end to a pin 29 in the baseboard 20. Rotation of the knob 7 to operate the distance-finder shifts the fulcrum 12 to a position corresponding to the distance. On projection of the baseboard the lens front is moved by the chain 28 to the correct position. The gearing between theknob 7 and the lever 3 renders the apparatus self-locking. Adjustment may be effected by unclamping the slide 23 from the lens front 14. by the screw 15, and final adjustment on the narrow extension 30 of the lever 3. The link 11 has an extension 27 forming a handle. It the lens front is pulled out by hand the linkwork 11, 21 may control a stop.

Title: Improvements in traverse carriage knock-off mechanism for lathes and like machine tools
IPC: B23Q5/52
Filed: 1936-07-30
Abstract: 478,745. Turning -lathes. JONES & LAMSON MACHINE CO. July 30, 1936, No. 21114. Convention date, Aug. 26, 1935. [Class 83 (iii)] A feed knock-off device 'for a lathe &c. carriage comprises a nut segment movable into or out of engagement with a rotary lead screw, a latch for holding the nut segment in engagement with the screw, a stop, a member movably carried by the carriage and adapted to engage the stop as the carriage approaches a desired traverse limit to be stopped while the movement of the carriage continues to operate means for releasing the latch. The hollow removable lead screw 2, Fig. 4, is secured to the driven shaft 1 and engaged by the nut segment 21, Fig. 2, for screwing feed. The nut segment is carried in a lever 15 pivoted at 12 and is adjustable for wear by a screw 26 and lock nut 27. The outer end of the lever is engaged by the forked end 92 of a hand lever 90, Fig. 4, which pivots about a sleeve 35 passing through the lever. A spring-pressed latch member 37 is housed within the sleeve and the projecting end 40 of this member is adapted to enter the end of a sleeve piece 41 to maintain the nut segment in engagement with the screw. The handle 90 is capable of limited rotation about the sleeve 35 and a slight depression effects, by means of a cam washer 94 and projecting studs 93, withdrawal of the latch from engagement with the sleeve 41, a further downward movement of the handle producing a rotation of the lever 15 and disengagement of the nut segment. This is effected automatically by a stud 85, Fig. 1, carried by a lever 80, pivoted at 81 to a bracket 83, striking the end 47 of an ejector 45, Fig. 4, which is moved against spring pressure within the sleeve 41 to push out the latch 37. The lever 80, Fig. 1, has a block 75 attached thereto which engages, through a tapered open-sided recess 76, the head 72 of an adjustable stop member 70 carried by a member 65 capable of sliding movement in the carriage. A further stop member 66 carried by the member 65 engages an adjustable dead stop 62 and thus arrests the member 65, but the carriage travels on a further distance and, through the engagement of the stop-head 72 with the slot in the member 75, the lever 60 is rocked to release the nut segment. The bracket 83 may be rotated in a direction outwardly from the plane of the paper, Fig. 1, to disengage the member 75 and stop-head 72 thus rendering the automatic stop ineffective. The Specification as open to inspection under Sect. 91 describes also a knock-off device, operating in a manner similar to the above, for use with a rack and pinion fed carriage. The operating lever in this instance, when moved to effect the automatic feed, engages a clutch for driving the pinion which is mounted on the carriage, and the lever is provided with a handle similar to the handle 90 having latch mechanism operated by the stop device 65. This subjectmatter does not appear in the Specification as accepted.
